Description

[Detailed Description of the Invention] The present invention relates to a soil block manufacturing device, and more particularly, to a soil block manufacturing device that is capable of sowing seeds in accordance with the number of soil blocks arrayed when sowing seeds into shaped soil blocks.

Soil blocking is a method of applying seeds or young seedlings to individual plants and growing them to the required size.
After growing, the seedlings can be transplanted to the field without changing the root environment, which allows the seedlings to grow well.
It is used in a cultivation method that has recently been in the spotlight. A soil block manufacturing device is used to form soil blocks accurately and efficiently.

Such soil block manufacturing equipment has already been proposed, but when the width of the soil block is selected and defined in three or four rows, the feeding means for sowing must be able to accommodate this.

This invention was made based on the above circumstances,
An object of the present invention is to provide an improved soil block manufacturing device in which the slide surface on the seed feeder side and the plurality of seed outlet holes in the corresponding gate plate can be selected in two ways by turning the gate plate upside down. It is something to do.
